Thanks for the reply, I do have the Marauders set but I will probably play Seasons so I will have to get it which is why I am open to any and all classes.Do you have the Marauder's set? If so, Cluster Arrow with a Bombardier's rucksack is still the way to go, however it's strong burst can one-shot most in Torment 6 now. You can almost get away without having to worry much about hatred generator in T6 for just quick, effortless clears by using Preparation with the Punishment rune and your Companion giving you hatred. Here's build I put together for a quick starter for an easy transfer over to 2.1.2, but I've got a couple of other builds as well that can be even more effective. http://www.diablofans.com/builds/17014-patch-2-1-2-release-day-build
There's a video at the end I posted and if you go towards the end of the video I have some gameplay that shows a fairly efficient way to waltz through Torment 6 content fairly easily. Hope this helps.
I actually saw the build you mentioned before I posted the question and took a look, definitely may give it a try. Ok, silly M6 question -- sentries no longer automatically shoot your spender right? You actually have to shoot and they are no longer considered pets so TnT or enforcer do not work. Am I right?
Any other build ideas I can give a look, maybe other classes?
